STORAGE BATTERY.

Specification of Letters Patent.

Patented Feb. 8, 1921.

Application filed August 16, 1919. Serial No. 317,943.

To all whom it may concern:

Be it known that I, BRUCE Foiu), a citizen of the United States, and aresident of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inStorage Batteries, of which the following is a specification.

The principal object of the present invention is to avoid theintroduction of dust and other foreign matter when filling or re-fillinga storage battery jar or container.

Other objects of the invention will appear from the followingdescription of the invention which will be claimed at the end hereof,but first explained in connect on with the accompanying drawings,forming part hereof and in which Figure 1, is a top or plan view of askirted stopper or plug, and

Fig. 2, is a view, principally in section, showing the skirted stopperin association with a cover having a funnel-filling open ng.

In the drawings 1 is a battery container or jar in which is arranged aplate structure 2, and which contains the electrolyte. 3, is a coverprovided with a filling opening 4, and having around the inlet of theopening 4, a depression 5, constituting an entrance funnel. 6, is a plugor stopper adapted to the opening and provided with a skirt 7, coveringthe depression. The plug or stopper 6 and skirt 7 may be of soft rubber,and when that is the case the skirt lies snugly on the face of thecover. The plug or stopper illustrated is of soft rubber and is coredout from its end, and it is shown as fitted into the tapered andchamfered wall of the inlet or opening 4, thus providing a tightclosure.

In fillin the jar or container with appropriate flui the depression 5serves as a funnel and if it contained dust or foreign matter the latterwould fall or be washed into the interior of the jar or container, whereits presence would be disadvantageous for reasons well understood bythose skilled in the art, but since the skirt covers the funneldepression 5, the same is protected from dust and dirt by the skirt 7which covers it and excludes foreign matter. The skirt being a provisionof the stopper or plug is always in position to cover the funnel portionwhen the stopper is in place for closing the inlet, and the skirt cannotbe lost or mislaid since it is attached to the plug. Again whilepossessed of the advantages referred to, the skirt adds little ornothing to the cost.

I claim:

1. In a storage battery container or jar the combination of a coverprovided with a filling opening and having around the inlet of theopening a depression constituting an entrance funnel, and a plug orstopper adapted to stop the opening and provided with a skirt coveringthe depression, substantially as described.

2. In a storage battery container or jar the combination of a coverprovided with a filling opening and having around the inlet of theopening a depression constituting an entrance funnel, a rubber plug orstopper adapted to stop the opening and provided with a soft rubberskirt covering the depression and lying on the face of the cover,substantially as described.

3. In a storage battery container or jar the combination of a coverprovided with a tapered and chamfered filling opening and having aroundthe inlet of the opening a depression constituting an entrance funnel,and a soft rubber plug or stopper fitted in the tapered and chamferedwall of the filling opening and provided with a soft rubber skirtcovering the depression and lying on the face of the cover,substantially as described.

BRUCE FORD.
